You reach out through your window and try to catch the bird. However, you slip and fall through the window plunging toward the ground below.
The bird has beautiful feathers. However, it is not interested in any food, meats or drink. It suddenly bites your hand and drank the blood from the wound. You quickly realize that this bird only drinks human blood. The bird then stares at you for a while and then, flies away with a golden feather left on the floor.
But the bird seems to have no interest in bread crumbs. You think it is reasonable that the bird born in a golden egg will be different from common birds and you try to speak with it.
After three days, the eggs disappear without a sign. You look at the nest, a bird flies towards you and tries to attack your hands!
